Abstract

Pyrazolato ligand is a good choice for the synthesis of germanous complexes that can be used in chemical vapor deposition (CVD)/atomic layer deposition (ALD) precursors for its special properties, such as the stability of the complexes based on the conjugated structure and the excellent volatility based on the low melting point. Here, several pyrazolato germanium(II) precursors were prepared and characterized. The correlation between the volatility and the amount of the substitute group was investigated. The thermal behavior was investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) experiments in order to demonstrate the enhancement of their thermal stability. The experiments indicated thermostability, and the volatilization of samples made them suitable as potential membrane materials..
